Carbon Dioxide, as it arises in only a small way, relative to natural sources of emission, such as and especially the Earth's inexorable processes of planetary volcanism, from our economically essential use of Coal in the generation of truly abundant and affordable electric power, is a valuable raw material resource.
Over the past several years, we have rather regularly documented the fact that Japan, as embodied in several of her universities and corporations, has been developing the science and technology for recycling Carbon Dioxide, as might be recovered from whatever source - - perhaps as occurs naturally, sometimes in quite surprisingly high concentrations, as a component of Natural Gas as it is extracted from natural geologic reservoirs - - and synthesizing from Carbon Dioxide a variety of gaseous and liquid hydrocarbons.
